EVO - In a snippet, check if ditto returns a value?

Hi
I have a ditto call that returns a list of offers, but sometimes we dont have offers. So I would like to check if the ditto call returns a result else I’ll call another ditto call or show a preset chunk.

Cheers

&noResults
Pur: no result returning text
Opt: $_lang[’no_documents’] | {{chunk}} | text
Def: $_lang[’no_documents’]
